The Institute's Annual Reports describe archival acquisitions and current holdings.
The Polish Institute has 2 large collections of materials that include some pertinent holdings: over 300 microfilms relating mostly to East European history and society, in 9 languages; and the oral and sound history collection, ca. 240 cassettes and tapes. Among the microfilms are manuscripts of Kazimierz Baginski on the trial of the 16 Polish Underground leaders in Moscow in 1945 (he was one of the accused), and of I. Nekrasov on Russian labor camps in Dmitrovsk and Samara. In the oral and sound history collection are the taped memoirs of General Michal Tadeusz Karaszewicz-Tokarzewski, commanding officer of the Polish Resistance Movement during World War II. Additions are expected in both these collections. There is also a biographical file which might hold data relating to the Russian Empire and Soviet Union.
